Abstract (en)

[origin: WO2022118004A1] An apparatus comprising: a bridge circuit for applying one or more pulse edges to a resonant circuit, the bridge circuit having a first limb in which a first connection point is connected to ground, and a second limb having a third transistor connected between a first power source and a second connection point and a fourth transistor connected between the second connection point and ground, wherein the resonant circuit comprises an inductive element and a capacitor connected in series between the first and second connection points, wherein the inductive element is for inductively heating a susceptor, wherein each applied pulse edge induces a pulse response between the capacitor and the inductive element of the resonant circuit, wherein the pulse response has a resonant frequency.
